Discriminatory dose determination for DMI fungicides for Clarireedia jacksonii and mycelial growth variation across active ingredients

Crop Science, Volume 65, Issue 1, January/February 2025.
Abstract In addition to cultural practices, dollar spot disease management requires frequent application of fungicides. Demethylation inhibitor (DMIs) fungicides are applied repeatedly to manage dollar spot in turfgrass systems. This facilitates reduction in DMI fungicide sensitivity among Clarireedia spp. populations. The objectives of this study were

Pathotypes and races of Pseudoperonospora cubensis: Two concepts of virulence differentiation

Plant Pathology, Volume 73, Issue 9, Page 2537-2547, December 2024.
Pathotypes and races are two different categories for the virulence variation assessment, which should be clearly defined, recognized and used within international scientific and breeding communities. Abstract Pseudoperonospora cubensis, causal agent of cucurbit downy mildew, is a common and highly variable pathogen of cucurbit vegetables.
